KlasseBBrände

Klasse B Brände refer to fires involving flammable liquids. This classification is part of an international system used to categorize fire types, aiding in the selection of appropriate firefighting agents and techniques. Common examples of Class B flammable liquids include gasoline, oil, grease, alcohol, and solvents. These substances ignite easily and can spread rapidly.

The primary hazard associated with Class B fires is the volatile nature of the liquids, which can produce flammable vapors. Extinguishing these fires requires agents that can smother the flames by separating the fuel from the oxygen supply or by cooling the fuel below its ignition temperature. Suitable extinguishing agents for Class B fires typically include foam, dry chemical powders, and carbon dioxide (CO2). Water can sometimes be used, but only in a finely atomized spray, as a solid stream of water can spread the burning liquid and worsen the fire.

Understanding Class B fire hazards is crucial for safety protocols in industrial settings, laboratories, garages, and kitchens where flammable liquids are commonly found. Proper storage, handling, and fire prevention measures are essential to mitigate the risks associated with these types of fires. Fire extinguishers are often color-coded or labeled to indicate their suitability for different classes of fire, with Class B extinguishers being specifically designed for these situations.
